2017-21121. Air Plan Approval; South Carolina; Interstate Transport (Prongs 1 and 2) for the 2010 1-Hour NO2

AGENCY:

Environmental Protection Agency.

ACTION:

Final rule.

SUMMARY:

The Environmental Protection Agency (EPA) is taking final action to approve a revision to the South Carolina State Implementation Plan (SIP), submitted by the South Carolina Department of Health and Environmental Control (DHEC), on December 7, 2016, addressing the Clean Air Act (CAA) interstate transport (prongs 1 and 2) infrastructure SIP requirements for the 2010 1-hour Nitrogen Dioxide (NO₂) National Ambient Air Quality Standard (NAAQS). The CAA requires that each state adopt and submit a SIP for the implementation, maintenance, and enforcement of each NAAQS promulgated by EPA, commonly referred to as an “infrastructure SIP.” Specifically, EPA is taking final action to approve South Carolina's December 7, 2016, SIP submission addressing prongs 1 and 2 to ensure that air emissions in the State do not significantly contribute to nonattainment or interfere with maintenance of the 2010 1-hour NO₂ NAAQS in any other state.

DATES:

This rule will be effective November 2, 2017.

SUPPLEMENTARY INFORMATION:

I. Background

By statute, SIPs meeting the requirements of sections 110(a)(1) and (2) of the CAA are to be submitted by states within three years after promulgation of a new or revised NAAQS to provide for the implementation, maintenance, and enforcement of the new or revised NAAQS. EPA has historically referred to these SIP submissions made for the purpose of satisfying the requirements of sections 110(a)(1) and 110(a)(2) as “infrastructure SIP” submissions. Sections 110(a)(1) and (2) require states to address basic SIP elements such as requirements for monitoring, basic program requirements, and legal authority that are designed to assure attainment and maintenance of the newly established or revised NAAQS. More specifically, section 110(a)(1) provides the procedural and timing requirements for infrastructure SIPs. Section 110(a)(2) lists specific elements that states must meet for the infrastructure SIP requirements related to a newly established or revised NAAQS. The contents of an infrastructure SIP submission may vary depending upon the data and analytical tools available to the state, as well as the provisions already contained in the state's implementation plan at the time in which the state develops and submits the submission for a new or revised NAAQS.

Section 110(a)(2)(D) has two components: 110(a)(2)(D)(i) and 110(a)(2)(D)(ii). Section 110(a)(2)(D)(i) includes four distinct components, commonly referred to as “prongs,” that must be addressed in infrastructure SIP submissions. The first two prongs, which are codified in section 110(a)(2)(D)(i)(I), are provisions that prohibit any source or other type of emissions activity in one state from contributing significantly to nonattainment of the NAAQS in another state (prong 1) and from interfering with maintenance of the NAAQS in another state (prong 2). The third and fourth prongs, which are codified in section 110(a)(2)(D)(i)(II), are provisions that prohibit emissions activity in one state from interfering with measures required to prevent significant deterioration of air quality in another state (prong 3) and from interfering with measures to protect visibility in another state (prong 4). Section 110(a)(2)(D)(ii) requires SIPs to include provisions ensuring compliance with sections 115 and 126 of the Act, relating to interstate and international pollution abatement.

On January 22, 2010, EPA established a new 1-hour primary NAAQS for NO₂ at a level of 100 parts per billion, based on a 3-year average of the 98th percentile of the yearly distribution of 1-hour daily maximum concentrations. See 75 FR 6474 (February 9, 2010). This NAAQS is designed to protect against exposure to the entire group of nitrogen oxides (NO_X). NO₂ is the component of greatest concern and is used as the indicator for the larger group of NO_X. Emissions that lead to the formation of NO₂ generally also lead to the formation of other NO_X. Therefore, control measures that reduce NO₂ can generally be expected to reduce population exposures to all gaseous NO_X which may have the co-benefit of reducing the formation of ozone and fine particles both of which pose significant public health threats.

States were required to submit infrastructure SIP submissions for the 2010 1-hour NO₂ NAAQS to EPA no later than January 22, 2013. For comprehensive information on 2010 1-hour NO₂ NAAQS, please refer to the Federal Register notice cited immediately above.

In a notice of proposed rulemaking published August 15, 2017 (82 FR 38646), EPA proposed to approve South Carolina's December 7, 2016, SIP submission concluding that its SIP adequately addresses prong 1 and prong 2 requirements for the 2010 1-hour NO₂ NAAQS. South Carolina provided the following reasons for its determination: (1) The SIP contains state regulations that directly or indirectly control NO_X emissions; (2) all areas in the United States are designated as unclassifiable/attainment for the 2010 1-hour NO₂ NAAQS; (3) monitored 1-hour NO₂ design values in South Carolina and surrounding states (Georgia, North Carolina, and Florida) are below the 2010 standard; and (4) point source emissions of NO_X in the State have trended downward. All other applicable infrastructure SIP requirements for South Carolina for the 2010 1-hour NO₂ NAAQS have been addressed in separate rulemakings. See 80 FR 14019 (March 18, 2015), 81 FR 56512 (August 22, 2016), and 81 FR 63704 (September 16, 2016).

The details of South Carolina's submission and the rationale for EPA's action are explained in the August 15, 2017, notice of proposed rulemaking. Comments on the proposed rulemaking were due on or before September 14, 2017. EPA did not receive any adverse comments on the proposed action.

II. Final Action

As described above, EPA is taking final action to approve South Carolina's December 7, 2016, SIP revision addressing prongs 1 and 2 of CAA section 110(a)(2)(D)(i) for the 2010 1-hour NO₂ NAAQS. EPA is taking final action to approve this portion South Carolina's infrastructure SIP submission because South Carolina's SIP includes adequate provisions to prevent emissions sources within the State from significantly contributing to nonattainment or interfering with maintenance of this standard in any other state.

III. Statutory and Executive Order Reviews

Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. See 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the CAA. This action merely approves state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this action:

• Is not a significant regulatory action subject to review by the Office of Management and Budget under Executive Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
• Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
• Is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.);
• Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4);
• Does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);
• Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);
• Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001);
• Is not subject to requirements of section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the CAA; and
• Does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994).

In addition, this action for the state of South Carolina does not have Tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because it does not have substantial direct effects on an Indian Tribe. The Catawba Indian Nation Reservation is located within the State of South Carolina. Pursuant to the Catawba Indian Claims Settlement Act, S.C. Code Ann. 27-16-120, “all state and local environmental laws and regulations apply to the [Catawba Indian Nation] and Reservation and are fully enforceable by all relevant state and local agencies and authorities.” However, EPA has determined that this action does not have substantial direct effects on an Indian Tribe because it is not approving any specific rule, but rather determining that South Carolina's already approved SIP meets certain CAA requirements. EPA notes this action will not impose substantial direct costs on Tribal governments or preempt Tribal law.

The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this action and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register. A major rule cannot take effect until 60 days after it is published in the Federal Register. This action is not a “major rule” as defined by 5 U.S.C. 804(2).

Under section 307(b)(1) of the CAA, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by December 4, 2017. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this action for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such rule or action. This action may not be challenged later in proceedings to enforce its requirements. See section 307(b)(2).
